Diseño de estructura de minibús eléctrico urbano mediante optimización estructural y pruebas estáticas virtuales de resistencia usando software Inspire y Simsolid de Altair

Abstract

The structural analysis of the bodywork of an urban electric minibus in Simsolid software and the validation of data through different load cases in different surface distributions has created the feasibility of developing structural bodywork projects oriented to the Ecuadorian regulation INEN 1323:2009 whose power train is electric, this because the mobility in Ecuador with the use of alternative energies is restricted for 2025, where it is established that public mobility vehicles must use alternative energies. The structural analysis that starts with a sketching process, goes through the topological optimization through simple geometries obtained in Altair's Inspire software where it shows the distribution of material highlighting frames and triangular geometric figures for the side walls according to the applied loads, the geometry design with local commercial profiles through Autodesk's Inventor structure generator, the selection of the material in Ecuador and the simulation by means of Simsolid that use of extended FEM, external approximations where it is necessary to create a geometry in the meshing resulted in the creation of several scenarios varying the distribution in the load application that provide adequate results for the structural design of an electric minibus.
